Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD with large balloons (10-15 mm) after limited EST for retrieval of choledocholithiasis. From February 2005, we have performed EBD with limited EST for retrieval of common bile duct (CBD) stones. The patients who admitted with hyperamylasemia and gallstone pancreatitis were excluded. In cases without CBD dilation, EPBD with 12 mm for 40 seconds was performed. And in cases with CBD dilation, we dilated the sphincters with 15 mm sized balloon for 40 seconds. Total 22 patients (11 of male) were performed EBD with limited EST for retrieval of CBD stones. The median diameter of the stones was 10 mm (5-25 mm). Ten cases had multiple stones and 6 cases periampullary diverticuli. Successful stone removal in the initial session of ERCP with EBD was accomplished in 16 patients (72.7%). And complete retrieval of bile duct stones was achieved in all patients with repeated ERCP. In the aspect of complications, any episodes of perforation, bleeding was not developed. Only one case of mild grade of post-procedural pancreatitis was noted. However, post-procedural hyperamylasemia was developed in 16 cases (68.2%). EBD with larger balloon seems to be a feasible and safe alternative technique for conventional EST in CBD stone extraction.

Massive postpartum haemorrhage after Cesarean section for placenta previa is a common occurrence. The bleeding is usually from the placental bed at the lower uterine segment. Uterine tamponade has a role in the management of such patients especially when fertility is desired. We describe here a case of massive postpartum haemorrhage, which was managed, with the use of a Sengstaken-Blakemore tube. This allowed us to avoid a hysterectomy for a young primiparous patient.

OBJECTIVETo investigate the risk factors of vaginal dilators by 567 adverse event reports, and to provide a reference for the reasonable use.

METHODSWith retrospective case study, analyzed 567 reports induced by vaginal dilators by National Adverse Drug Reaction Monitoring Center in 2012.

RESULTSExpected treatment of disease might be relevant with severity of adverse events, while age was not the related factor; the influencing factor of consequences of grading was the classification of the cause of adverse events.

CONCLUSIONMonitoring should be strengthen in order to reduce or avoid the vaginal dilator adverse events.

BACKGROUND/AIMS: The aim of this study was to evaluate the outcome of endoscopic dilation for benign anastomotic stricture after radical gastrectomy in gastric cancer patients. METHODS: Gastric cancer patients who underwent endoscopic balloon dilation for benign anastomosis stricture after radical gastrectomy during a 6-year period were reviewed retrospectively. RESULTS: Twenty-one patients developed benign strictures at the site of anastomosis. The majority of strictures occurred within 1 year after surgery (95.2%). The median duration to stenosis after surgery was 1.70 months (range, 0.17 to 23.97 months). The success rate of the first endoscopic dilation was 61.9%. Between the restenosis group (n=8) and the no restenosis group (n=13), there were no significant differences in the body mass index (22.82 kg/m2 vs 22.46 kg/m2), interval to symptom onset (73.9 days vs 109.3 days), interval to treatment (84.6 days vs 115.6 days), maximal balloon diameter (14.12 mm vs 15.62 mm), number of balloon dilation sessions (1.75 vs 1.31), location of gastric cancer or type of surgery. One patient required surgery because of stricture refractory to repeated dilation. CONCLUSIONS: Endoscopic dilation is a highly effective treatment for benign anastomotic strictures after radical gastrectomy for gastric cancer and should be considered a primary intervention prior to proceeding with surgical revision.

A benign anastomotic stricture is a common complication of upper gastrointestinal (UGI) surgery and is difficult to manage conservatively. Fluoroscopically guided balloon dilation has a number of advantages and is a safe and effective procedure for the treatment of various benign anastomotic strictures in the UGI tract.

PURPOSE: This study was undertaken to evaluate the long-term treatment of esophageal strictures in children with corrosive esophagitis and to determine the effect of self-bougienage on recurrent strictures. MATERIALS AND METHODS: We reviewed the medical records of nine children that were treated for corrosive esophageal strictures from May 2000 to May 2008. Six males and three females were included and their average age was 30 months. Six patients had ingested acids, two patents had ingested alkali, and one ingested an unknown agent. RESULTS: The interval between caustic ingestion and esophageal stricture ranged from one to eight weeks. The average length of the esophageal strictures was 3.8 cm (range, 1 to 9.2 cm). Four patients had a long segment stricture (longer than 5 cm) and one patient had multiple strictures. The most common site of involvement was the upper third followed by the mid third of the esophagus. Eight patients received repeated dilatation using a balloon catheter or bougie dilator. Among the eight patients, two patients had complete resolution of symptoms and six patients required surgery. Among five patients that developed restenosis of the esophageal anastomosis site, three patients had improved symptoms after self-bougienage and two patients had improved symptoms with repeated balloon dilatation or endoscopic bougienage. There were no complications in these patients. CONCLUSION: Although a small number of patients were studied, self-bougienage was safe, less invasive, and effective for the management of esophageal restenosis in patients who required frequent dilation after surgery.

OBJECTIVE: We wanted to present the results of percutaneous management of ureteral injuries that were diagnosed late after cesarean sections (CS). MATERIALS AND METHODS: Twenty-two cases with 24 ureteral injuries that were diagnosed late after CS underwent percutaneous nephrostomy (PN), antegrade double J (DJ) catheter placement and balloon dilatation or a combination of these. The time for making the diagnosis was 21 +/- 50.1 days. The injury site was the distal ureter in all cases (the left ureter: 13, the right ureter: 7 and bilateral: 2). Fifteen complete ureteral obstructions were detected in 13 cases. Ureteral leakage due to partial (n = 4) or complete (n = 3) rupture was noted in seven cases. Two cases had ureterovaginal fistula. All the cases were initially confirmed with antegrade pyelography and afterwards they underwent percutaneous nephrostomy. Balloon dilatation was needed in three cases. Antegrade DJ stents were placed in 10 cases, including the three cases with balloon dilatation. Repetititon of percutaneous nephrostomy with balloon dilatation and DJ stent placement was needed in one case with complete obstruction. All the cases were followed-up with US in their first week and then monthly thereafter for up to two years. RESULTS: Eighteen ureters (75%) were managed by percutaneous procedures alone. A total of six ureter injuries had to undergo surgery (25%). CONCLUSION: Percutaneous management is a good alternative for the treatment of post-CS ureteral injuries that are diagnosed late after CS. Percutaneous management is at least preparatory for a quarter of the cases where surgery is unavoidable.

OBJECTIVE: We wanted to evaluate the therapeutic efficacy of the percutaneous balloon dilatation and large profile catheter maintenance method for the management of patients with anastomotic biliary strictures following liver transplant. MATERIALS AND METHODS: From May 1999 to June 2003, 12 patients with symptomatic benign biliary stricture complicated by liver transplantation were treated with the percutaneous balloon dilatation and large profile catheter maintenance method (1-6 months). The patients were eight males and four females, and their ages ranged from 20 to 62 years (mean age: 44 years). Ten patients underwent living donor liver transplantation and two underwent cadaveric liver transplantation. Postoperative biliary strictures occurred from two to 21 months (mean age: 18 months) after liver transplantation. RESULTS: The initial technical success rate was 92%. Patency of the bile duct was preserved for eight to 40 months (mean period: 19 months) in 10 of 12 (84%) patients. When reviewing two patients (17%), secondary balloon dilatations were needed for treating the delayed recurrence of biliary stricture. In one patient, no recurrent stenosis was seen during the further 10 months follow-up after secondary balloon dilatation. Another patient did not response to secondary balloon dilatation, and he was treated by surgery. Eleven of 12 patients (92%) showed good biliary patency for 8-40 months (mean period: 19 months) of follow-up. CONCLUSION: The percutaneous balloon dilatation and large profile catheter maintenance method is an effective therapeutic alternative for the treatment of most biliary strictures that complicate liver transplantation. It has a high success rate and it should be considered before surgery.
